It's kind of a combination between a SPA and a static website.
We generate all the HTML pages so that they can serve as entrypoints, so when you go to https://gocardless.com/features we serve a fully rendered page to the browser, plus we load the rest of the website (that's why it's super snappy after the initial page load).
If you don't have javascript enabled, you'll still get fully rendered page.

May be this is why your site is so fast. SPA apps are not entirely static.
